Fuel is a material such as coal, gas, or oil that is burned to produce heat or power. For many years gasoline and diesel have been the main source of fuel for cars and other motorized technology. These types of fuels are called fossil fuels and are non-renewable. Fossil fuels are a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms. Non-renewable fuels are organically-derived fuels.
Coal like most of our current energy fuels is finite, it cannot be replenished once it is burned and cannot be considered a renewable resource. Most people do not know that coal is just decomposed plant and animal matter that over millions of years is gradually transformed into hard black solids by the sheer weight of the earth. Coal is typically burned to create steam, which is then piped at high pressure over a turbine, causing it to rotate, producing electricity. So what does coal have to do with going Green? Coal produces over 57% of the electricity generated in the United States.
Fossil Fuels Report What are Fossil Fuels? The Combustion of fossil fuels Fossil fuels are made up of hydrocarbons which are compounds that contain the elements hydrogen and carbon. Examples are methane, CH4, propane, C3H8 and butane, C4H10. Hydrocarbons readily burn or undergo combustion reactions. Combustion may be complete or incomplete.
In Ohaake in New Zealand about 320 gm of C02 is produced for each KW hour of electricity produced against 950 to 960 gm. if coal was used. Limitations Geothermal energy is a proven economical resource with energy technology. It has some environmental problems: 1. The steam brings hydrogen sulphide gas to the surface and pollutes the air unless controls are instituted.
There is about 1700 kPa (250 psi) pressure in the tank when full. Acetylene when combined with oxygen burns at a temperature of 3200 °C to 3500 °C (5800 °F to 6300 °F), highest among commonly used gaseous fuels. As a fuel acetylene's primary disadvantage, in comparison to other fuels, is high cost. As acetylene is unstable at a pressure roughly equivalent to 33 feet/10 meters underwater, water submerged cutting and welding is reserved for hydrogen rather than acetylene. Compressed gas cylinders containing oxygen and MAPP gas.
“The fuels are made by separating and chemically changing petroleum compounds, a process referred to as refining (Farrauto). Diesel and gasoline are both made up of many different hydrogen-carbons, which are “compounds of consisting of hydrogen and carbon elements” (Farrauto). However diesel carbon atoms are in longer chains than gasoline. “Diesel chains have 14 carbon atoms whereas gasoline chains have 9” (Farrauto). The main differences between diesel and gasoline are as follows: “a) A diesel Engine takes air into the cylinder and compresses it.
So this is the reason why price of fossil flues will become higher. You can see it in P.1. (P.1) However, alternative energy will become cheaper. People will use alternative energy instant of fossil flues. In fact, the price of solar energy is falling since 2008.
At one point, the idea of using a car that was electric powered may have seemed outrageous. Several questions emerged, such as: can it be done; would it work; how would it work; when would it happen; and how much would it cost. “Record-high oil prices have pushed consumers towards fuel-efficient vehicles and prompted many governments to consider electric transport as a way to escape their dependence on imported petroleum and to address climate change” (ebscohost.com). Here are a few of the many reasons why cars should be more efficient. First, cars should be more efficient because the cost to the consumer may decrease.
In an era where depletion of fossil fuels a major problem and pollution an even bigger issue,it is only the alternate sources of energy which can meet the energy requirements of the future. So today i gaurav grover of class 10-b is here to share my views on the topic alternative sources of energy. Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas.
Most of the energy we use today comes from fossil fuels. Coal, oil, and natural gas are all fossil fuels created several millions of years ago by the decay of plants and animals. These fuels lie buried between layers of earth and rock. While fossil fuels are still being created today by underground heat and pressure, they are being consumed much more rapidly than they are created. Therefore, sometimes in the future we will run out of them.
